Alien Run Mountain Bike Trails

Located just outside of Aztec, the Alien Run Trail System provides mountain bikers with the opportunity to experience a variety of trails in a high desert landscape! Named for a nearby rumored UFO crash site, the approximately 20 miles of trails provide a wide variety of experiences including playful and flowing single track, exposed sections along the tops of escarpments, extensive slickrock areas, and loose and rocky challenging trail with significant changes in elevation.
